and demonstrating technological abilities.
Explanation:
The Renaissance period is the period of great development and self awareness among people leading to great technological breakthrough and development. <em>The renewed interest in the classics are part of the reasons why their is a shift from Middle Ages. For examples the works of Michalengo, Da vinci etc are what inspired people.</em>
I think that it caused more tension sectionally because there was already tension between slave and non-slave states so it's growing economy just added more. Hope this helped!! Have a good day :)
